Dr. Frizzell uses sealants mostly on children whose premolars and molars are coming in. Placed on the grooves of these back teeth that are hard to reach with brushing and flossing, sealants help prevent tooth decay during the vulnerable ages of six to 14. Adults without cavities on their molars may also be good candidates.
The painless procedure begins with a thorough cleaning. After each tooth is dried, the dentist places an acid solution on the chewing portions to roughen up the surface. This enables better absorption of the sealing agent. The teeth are rinsed and dried again, then the dentist paints the sealant onto the enamel, sometimes uses a curing light to bond the sealant.
Sealants are effective for as long as 10 years. At regular cleanings, dentists inspect the sealant for chipping or wearing, and teeth may be resealed if necessary during that time.
